Specification of Letters Patent.

Patented July 19, 1921.

Application led January 3, 1919. Serial No. 269,440.

To al I f1.0 hom 'it may concern Be .it known that we, HARRY A. JONESand lilmvAno WV. S'rRUvE, citizens of the United States, residing atParsons, in the county of Labette and State of Kansas, have inventedcertain new and useful Im rovements in Adjustable Chain Oil- Bearings,of which the following is a specification.

This invention relates to lubrication, and more especially to devicesfor carrying a lubricant to a bearing by means of a conveyer chain; andthe object of the same is to effectively lubricate a shaft whichrevolves at a high rate of speed.

Another object is to provide, in proximity to said shaft bearing, asecond bearing for the shaft of an idler wheel under which passes a beltleading to a pulley on the shaft first mentioned.

Another object is to provide means for adjusting the position of thelast-named bearing so as to alter the position of the idler andtherefore the tension of the belt.

These and other objects are carried out by the construction set forth inthe following specification and claims, and shown in the accompanyingdrawings, wherein Figure 1 is a side elevation, and

Fig. 2 is a plan view of parts showing the relative position of the twobearings, while Fig. 3 is an end view of the same,

Fig. 4 is a sectional view of the main shaft bearing on the line 4-4 ofFig. 2,

Fig. 5 is a plan View of said bearing with its cap removed, parts beingshown 1n section, and

Figs. 6 and 7 are details in plan view and olvation of the adjustablebearing for the 1 er.

Referring by numerals to the said drawings, l designates the base of themain frame, 2 the inclined portion of its top, and 3 the flat topportion pierced with two rows of holes 4. The numeral 5 designates thebase of the main shaft bearing, which base is provided with holes 6adapted to register with certain of the holes .4 so that screws or bolts7 may be passed through them, and by this means the bearing 5 isadjustable longitudinally on the top 3 of the main frame. The base 1 ofsaid frame will itself have holes 8 through which will ass screws orbolts fastening it upon the sills or licor by which the entire frameworkand the parts carried thereby are su ported.

The main bearing as seen in Figs. 4 and 5) consists of a lower part '10rising from the base 5, and having out-turned flanges 11, and a cap 12overlying the lower part and having out-turned fianges 13, the twoflanges being detachably connected by screws or bolts 14 passing throughalined holes 15 1n said flanges. Internally, the cap may be shaped tofit closely over the main shaft 16, butwe have shown it as babbitted` onits interior as at 17 and I reserve thewidest latitude in this respect.Internally, the lower part 10 of the bearing has formed between its endsa considerable chamber 18 as best seen in Fig. 4, the ends of thechamber being closed by the end walls of this part which rise highenough to underlie the shaft 16, babbitting 19 being illustrated in Fig.4 at this oint. i

A chain 20 overlies the shaft and travels yin a channel 21 in the cap12, the chain being endless and considerably longer than thecircumference of the shaft so that its lower part hangs within thechamber 18, while its upper part rests on the top of the shaft as willbe obvious. Any suitable means may be provided for filling the chamberwith lubricating oil and for withdrawing the same, or for withdrawingsediment which may collect therein. In Fig. 4 we have shown an outletopening closed by a plug 22, but we do not wish to be limited to thesedetails. The end 23 of the bearing may be closed if this bearing is atthe end of the shaft 16, although, as seen in Figs. 2 and 3, the end mayhave a plug 24 which is itself tubular so as to receive the stem of anoil or greasecup 25. Thus the plug 24 receives the end thrust of theshaft 16, and lubricant is applied to its extremity. The chain travelingin oil carries the same upward over the shaft continually and into thechannel 21, whence it spreads in both directions longitudinally alongthe shaft and over the wear faces, whether the latter are babbitted ornot. I1nmediate access is gained to this bearing by removing the boltsor screws 14 and lifting off the cap 12. We might say that we haveapplied this chain forni of lubricator to the shaft of a rapidlyrevolving saw, but we do not wish to be limited in the use of the same.

In connection with this invention, we prefer also to employ a movablebearing for the shaft of an idler wheel which constitutes a tightenerfor the belt leading to the driven pulley on said. sawfshaft. As seen.in Fig. l,

the idler frame 31 rises from the inclined portion 2 of the top of themain frame, and is made up ofV two legs and a removable cap piece 32held on their upper ends by screws 33. The cap piece has a nut 34through which passes a screw 35 swivelly mounted at its lower end in anopening 36 in the top plate of a block 37 which is channeled at oppositesides as shown at 38 in Fig. G to travel on guides 39 extendinglongitudinally along the inner faces of the legs of the idler frame.Thus when this screw 35 is turned in one direction or the other, theentire block is adjusted vertically` within said frame, and accordinglythe bearing for the .idler shaft is moved either up or down with respectto the main frame and the bearing for the saw-shaft 16. The idler shaftbearing, indicated at' 40' in Fig. 1 is carried within an opening in theblock 37, in which opening it is adjusted by screws 41 at its sides and.t2 beneath it, all screws being threaded through the block and againstthe bearing so that the latter may be adjusted to take up wear and to`accurately center the idler shaft, even after the block has beenadjusted in its frame. that the bearing for the main shaft 16 isiinclined a little to the left, whereas the frame in which is mountedthe bearing for the idler shaft is inclined a little to the right, andboth rise from the main framework which is mounted on the sills or othersupports. Itv will be observed from Fig. 2 that the idler frame 31 risesfrom one side of the top portion 2 of the main framework, and it will beclearto those who are familiar with erecting machinery that only thosemain frames adjacent the driven pulley on the main shaft Willv needy tohave the idler frames, because the idler shaft is not extended the fulllength of the main shaft. The latter, as suggested above, usuallycarries a circular saw and will be rotated at a high rate of speed. Theadjustment of the bearing for the idler It will be observed from Fig. l.

position wheel upon the main driving and arrangement and combination ofparts,

materials, dimensions, etc., as may prove expedient and fall within thescope of the appended claims.

Having thus fully described our invcn tion, what we cla-iin as new anddesire to secure by Letters Patent, is

l. The combination of a quadrangular frame having one side parallel toits base and another side at an acute angle thereto, a main bearingmounted on the first nicntioned side, an idler frame mounted on thesecond mentioned side so as to be at right angles thereto, and an .idlerbearing' mounted in the idler frame.

2. The combination of a main frame having' part of its top flat and theremaining portion inclined, a main bearing adjust-abi)Y mounted on theflat portion, an idler franie rising` from and at right angles to theinclined portion of said top and composed ol. two legs having` guidesalong their interior. a cap plate connecting the upper ends` andcontaining a nut, a screw threaded in the nut, a block having channelsadjustable on said. guides, the lower end of the screw being swiveled insaidblock, and an idler shaft bearing adjustably mounted within saidblock, for the purpose specified.

In testimony whereof we ailix our signatures in presence of twowitnesses.
